Ultra Compact DP-IQ Modulator Bias Controller Automatic Bias Controller
Feature
• Panguva imwe chete inopa matanhatu otomatiki bias voltages yeDual Polarization IQ modulators
•Modulation format yakazvimirira:
SSB, QPSK, QAM, OFDM yakasimbiswa.
•Plag uye Tamba:
Hapana manual calibration inodiwa Zvese otomatiki
•Ini, Q maoko: controll paPeak uye Null modes High extinction ratio:50dB max1
•P ruoko: controll paQ+ uye Q- modes Kururama: ± 2◦
•Yakaderera chimiro: 40mm(W) × 29mm(D) ×8mm(H)
•Kugadzikana kwepamusoro: kushandiswa kwedhijitari zvizere Zviri nyore kushandisa:
•Kushanda nemaoko nemini jumper 2
Flexible OEM mashandiro kuburikidza neUART /IO
• Nzira mbiri dzekupa bias voltages: a.Automatic Bias Control b.User defined bias voltage
Application
•LiNbO3 nemamwe DP-IQ modulators
• Coherent Transmission
1Iyo yakanyanya kutsakatika reshiyo inotsamira uye haigone kudarika 1 iyo system modulator yakanyanya kupera reshiyo.
2Kushanda kweUART kunongowanikwa pane imwe vhezheni yemutongi.
